To ensure your high-frequency designs perform as intended, you need to look beyond simple voltages and currents. A Vector Network Analyser (VNA) allows you to see how RF and microwave components, from simple cables to complex antennas, interact with signals by measuring both the magnitude and the phase of transmitted and reflected waves. Telonic’s range of high-performance VNAs is engineered for professionals who demand precision in the frequency domain. Whether you are tuning a filter for a telecommunications base station or verifying the impedance matching of a PCB trace, our analysers provide the dynamic range and calibration accuracy essential for modern wireless and high-speed digital engineering.

Why Choose a Vector Network Analyser?

Complete S-Parameter Analysis: Simultaneously measure reflection (S11) and transmission (S21) to fully characterise RF components.
Phase & Magnitude Insight: Capture both signal strength and phase data for precise Smith Chart plotting and group delay analysis.
Time-Domain Reflectometry: Pinpoint the exact physical location of impedance mismatches or faults within a transmission line.
Superior Measurement Accuracy: Advanced error correction and calibration techniques ensure laboratory-grade results across the frequency spectrum.

Core Applications

Antenna Matching & Tuning: Optimising VSWR and Return Loss to ensure maximum power efficiency and signal range.
Filter & Component Testing: Verifying insertion loss, bandwidth, and out-of-band rejection for RF conditioning hardware.
Wireless Network Verification: Assessing signal integrity and crosstalk in modern telecommunications and IoT infrastructure.
Cable & Connector Validation: Testing high-frequency cables and interconnects for loss and phase stability.
